2.1.
The IND780 Terminal is simple to use yet sophisticated, with flexibility of
configuration to meet a variety of operating requirements. The setup menu system
provides the power of configuration in a user-friendly operational environment.
While reading this manual and operating the terminal, keep in mind that various
functions may or may not have been enabled for your installation, and that the
screens shown in this manual may vary from terminal to terminal, depending on
how it is set up and configured.
This document provides instructions for performing typical weighing operations on
the IND780 terminal.
Security
The IND780 supports the use of username/password for setup security at four levels.
• Administrator—An Administrator account has unlimited access to all areas of the operating and
setup system. There can be multiple Administrator accounts. There is a Primary Administrator
account, which can be changed but never deleted. The terminal is pre-configured at the factory
with the Primary Administrator account with no password. The unit as configured at the factory
requires no login or password entry to enter the setup mode. All functions of the terminal are
available to all users until a password for the Primary Administrator account is set up.
When the Metrology switch is turned “on” (refer to the next section of this chapter), all users with
Administrator rights are reduced to the Maintenance level. This is done to protect metrologically
significant parameters that cannot be changed when the terminal is “approved.” Refer to the
IND780 Technical Manual Appendix B, Default Settings for the security level of each setup
parameter.
Once a password is set up, be sure to remember it. If the password is changed or forgotten,
access to the setup menu will not be available. Be sure to protect the password from access by
unauthorized personnel. The password provides access to the entire setup menu. However, if
the metrology switch is placed in the approved position, metrologically significant settings
cannot be modified.
• Maintenance—Access is generally the same as the Administrator level with the exception of
access to metrologically significant areas of the setup.
• Supervisor—Access is generally limited to editing tables and setting time and date.

Operating Instructions
• Operator—One default operator account is provided. Sites with validation requirements might
create many operator accounts, each with a username and password entry requirement. The
Operator-class of security is the most restrictive, allowing the user to use and view, but not
change records within tables.
If a password has been programmed for the default Administrator username in Setup, and all other
users have a password assigned, a login screen is presented whenever the Setup softkey is
pressed. A valid username and password must be entered. Depending on the access level of the
user logged in, setup screens may be visible only, or visible and available for modification.
If a login fails, the display exits the login page and returns to the home screen.
2.1.1.
Metrology Switch
If the metrology switch (S1) is placed in the approved position (On), changes to the Scale branch
of setup and other metrologically significant areas are not permitted. Access to the metrology switch
may be sealed in conformity with local regulations in “legal-for-trade” applications. Figure 2-1
shows the location of the metrology switch, immediately adjacent to the Compact Flash card and
PLC module location.

Explanation
When multiple scales are connected to the indicator, this button permits the user
to switch between them, including the Sum Scale if one is configured.
To select a specific scale, enter the scale number using the numeric keys and
press the Select Scale function key.
When the scale platform or weighbridge is empty, the terminal should indicate
zero. The gross zero reference is recorded during calibration. Press the ZERO key
to capture a new gross zero reference point if pushbutton zero is enabled in
configuration and the weight is within the zero range. Pressing ZERO when a
Tare has been taken and the scale is in Net mode will cause an error message
to display – “Zero Failed – Scale in Net Mode. Press ENTER to continue.”
Tare is the weight of an empty container. Tare is normally used to determine the
net weight of the contents of a container. Press the TARE key when an empty
container is on the scale. The terminal then captures the tare value and displays
a net weight of zero. The B/G display changes to read NET, and a box appears
at upper right in the display (Figure 2-14), showing the tare value and units. As
the container is loaded, the terminal will display the net weight of the contents.
Pushbutton tare must be enabled to use the key in this manner.
Tare
When the empty weight of the container is a known value enter the tare directly
using the numeric keys, then press the TARE scale function key. The terminal will
display the net weight of the contents of the container. Keyboard tare must be
enabled in order to use this key in this manner.
To return to B/G (gross) mode after the TARE key has been pressed, press

selected template or report. When a demand print command is issued, “Printing”
appears in the system line for 3 seconds.
Alpha Keys
On some screens permitting data entry, when field requiring non-numeric input (such as a
password) is selected, softkeys and application keys function as alpha keys used to enter
alphabetic characters. Figure 2-5 shows an example of the initial alpha key screen, with the
softkeys shown to indicate their relationship to the display.
Figure 2-5: Alpha Keys and Softkeys
The alpha keys are automatically displayed when the cursor is moved into a data entry box that
supports alpha entry. The first set of softkeys shown is groups of upper-case letters (Figure 2-5).
Press the MORE DOWN key to view lower-case groups (Figure 2-6).
Figure 2-6: Lower Case Alpha Key Groups
In addition to those accessed via softkeys, additional sets of characters are accessible using the A3

of symbols. For each of these sets of characters, a group of four to six letters is shown per softkey.
To enter a character, press the softkey under the group that includes the required character. If the set
of keys shown does not include the required character, press the DOWN navigation key to view the
next set. Press the DOWN navigation key and UP navigation key as required until the set of keys
shows the required character. Note the MORE UP and MORE DOWN symbol to the right of the
softkeys (visible at right in Figure 2-5 and Figure 2-6), indicating that additional sets of characters
are available.
After pressing the softkey associated with the group of characters that contains the required
character, the characters above the softkey will change to show one character per softkey (in the
upper row) and application key (in the lower row). Examples of the possible displays are shown in
Figure 2-7, with the lower-case letter screen associated with the first softkey at the top, and all the

displayed on the screen simultaneously, in which case front keypad functions (tare, zero, etc.)
affect the selected scale.
Operating Instructions
Pressing the Select Scale button switches between the scale bases in sequence. To select a scale
directly, entering its number using the numeric keys, then press the Select Scale button. Figure 2-11
shows a home screen with three scales plus a Sum Scale, with a highlight indicating that Scale 3 is
selected.
Figure 2-11: Scale Selection
2.6.2.
Sum Scale
When configured in Setup (at Scale > Sum Scale > Type), the Sum Scale allows for a logical
measurement channel that works from the arithmetic sum of the weight values from two or more
scales. Each scale may have a different capacity and increment size, but they must all be
configured with the same units.
In general, the Sum Scale display behaves like any other independent physical scale channel.
However, any zero command issued to the Sum Scale is redirected to each of its component scale
channels. With regard to the weight display, if one scale included in the Sum Scale is overcapacity, both its display and the Sum Scale will show “^ ^ ^ ^ ^“. If a component scale is under
range, the display will also show “v v v v v“. These conditions are shown in the screen images in
Figure 2-12. In both cases, the Sum Scale is selected.

If one scale included in the Sum Scale is over-capacity and another is under range, the respective
scales will indicate their conditions accordingly, and the Sum Scale display will show “----------“,
indicating an invalid weight value. This condition is shown in Figure 2-13.
Figure 2-13: Summed Scales Simultaneously Over Capacity and Under Range

Zero
The Zero function is used to set or reset the initial zero reference point of the IND780. There are
three types of zero setting modes:
• Automatic Zero Maintenance (AZM)
• Power-Up
• Pushbutton
2.6.3.1.
Automatic Zero Maintenance
Automatic Zero Maintenance (AZM) enables the IND780 to compensate for the buildup of small
amounts of weight and track itself back to the center of zero. Within the AZM operating range
(programmable from 0.0 to 9.9 divisions), when the terminal is in a no motion condition it makes
small adjustments to the current zero reading to drive the weight reading toward the true center-ofzero. When the weight is outside of the programmed AZM range, this feature is not functional.
2.6.3.2.
Power-Up Zero
Power-Up Zero enables the IND780 terminal to capture a new zero reference point after power is
applied. If there is motion during a power-up zero capture function, the terminal will continue to
check for a no-motion condition until zero is captured.
Power-up zero can be disabled (RESTART on power up) or enabled (Reset on power up), and a
range above and below calibrated zero can be configured. The range is programmable from 0% to
100% of capacity and can include a positive range and also a range below calibrated zero.
2.6.3.3.
Pushbutton Zero
The pushbutton (semi-automatic) zero function can be accomplished by pressing the ZERO
scale function key, by programming a discrete input, by a PLC or serial command, or by an
application.
64057247 | 13 | 08/2014
METTLER TOLEDO IND780 User's Guide
2-17
Operating Instructions
The range for all types of semi-automatic zero is selectable (0% to 100%) plus or minus from
either the calibrated zero point (if power-up zero is disabled) or from the initial zero setting point (if
power-up zero is enabled).
Remote initiation of the semi-automatic Zero command is possible via a discrete input, an ASCII ‘Z’
command sent serially (CPTZ and SICS), a command initiated by the PLC interface, or from an
application.
2.6.4.
Tare
For detailed information about tare functionality when using SICS balances, please refer to the
SICS section in the IND780 Technical Manual Appendix D, Communication.
Tare is the weight of an empty container. A tare value subtracts from the gross weight
measurement, providing the computation of the net weight (material without the container). The tare
function can also be used to track the net amount of material being added to or removed from a
vessel or container. In this second case, the weight of the material in the container is included with
the tare weight of the container as tare. The display then reflects the net amount being added to or
removed from the vessel.
The tare value can be displayed with the net weight. The operation of this secondary display is
determined in Setup at Terminal > Display.

Pushbutton tare can be configured in Setup as enabled or disabled. When this feature is disabled,
the TARE scale function key
cannot be used to obtain a tare.

METTLER TOLEDO IND780 User's Guide
64057247 | 13 | 08/2014
If pushbutton tare is enabled, pressing the pushbutton TARE scale function key
initiates a
semi-automatic tare. The IND780 will attempt to perform a tare process. If it is successful, the
display changes to a zero net weight indication and the previous weight on the scale is stored as
the tare value. The net mode will be indicated on the display.
Several conditions could inhibit the pushbutton tare function:
• Motion—Pushbutton tare cannot be taken when the scale is in motion. If motion is detected
when a pushbutton tare command is received, the IND780 will wait up to three seconds for a
no-motion condition. If a stable (no motion) weight condition occurs before the three seconds
expire, the pushbutton tare command is executed.
If there is still motion at the end of three seconds, the command is aborted and a “Tare Failure
– In Motion” error displays.
• Pushbutton Tare Disabled—If pushbutton tare is configured as disabled, the TARE scale
function key will not initiate a semi-automatic tare.
• Negative Gross Weight—Any pushbutton tare attempted when the gross weight is at or below
zero is ignored and a “Tare Failed–Too Small” error displays. Ensure that the gross weight is
above zero.
2.6.4.2.
Keyboard Tare
A keyboard (preset) tare is a numeric tare that is entered manually through the numeric keypad,
received serially from a peripheral, or retrieved from the Tare Table memory. The preset tare value
cannot exceed the capacity of the scale. Data entered is interpreted to have the same units as the
current displayed value. Motion does not impact the entry of preset tare values.
Keyboard tare can be configured in Setup as enabled or disabled. When disabled, the numeric
keypad and the TARE scale function key
cannot be used to obtain a tare.
To manually enter a preset tare value, use the numeric keypad to enter the tare value (the entry will
display above the softkey icons) and press the TARE scale function key
. The tare display box
will include PT to indicate that a preset tare is in use.
If configured in Setup, remote equipment can enter a preset tare value using a serial command or
PLC command. (For further information, refer to the IND780 Technical Manual, Communication,
Configuration, the Serial and PLC Interface sections.)
If the preset tare is successful, the display changes to a net weight indication, and the entered
preset tare value is stored as the tare value in the Tare Table.
Several conditions could inhibit the preset tare function:
• Keyboard Tare Disabled—If keyboard tare is configured in Setup as disabled, the numeric
keypad and the TARE scale function key
cannot be used to obtain a tare.
• Over-Capacity or Under-Zero Condition—Preset tare is not allowed when the weight display
indicates over capacity or under zero conditions. Any preset tare attempted when the scale is
over capacity is ignored and a “Tare Failed – Over Cap” error displays. Any preset tare attempted
when the weight display indicates an under zero condition is ignored and a “Tare Failure –
Below Zero” error displays.
64057247 | 13 | 08/2014
METTLER TOLEDO IND780 User's Guide
2-19
Operating Instructions
Preset tare can be entered in free format. If the entered value does not match the displayed
weight decimal point location or display interval, the entered tare value is rounded to the nearest
display interval and the decimal point adjusted to match the gross weight. The rounding method
is that 0.5 or more of a display interval (d) is increased to the next display interval and 0.49 or
less of a display interval is decreased to the next lower display interval.
When entering a preset tare value less than 1.0, the operator can enter the data without the
leading zero (left of the decimal point), but all subsequent display, storage, or printing of this
value will include the leading zero. For example, a preset tare entry of .05 will display as 0.05.
If a preset tare has already been established and another preset tare is entered, the second
preset tare replaces the previous value (it does not add to the previous value). The replacement
tare can be larger or smaller than the original tare value.
2.6.4.3.
Tare Table
The IND780 terminal contains a tare table for storing tare weights that can be recalled by the
operator for use instead of manually entering them for each transaction. This is especially useful
when certain tare values are used repeatedly.
A description up to 40 characters long can be included with each record. This can be used to help
distinguish one tare record from another. Each tare record in the tare table also contains a
totalization field. When totalization is enabled for the tare table, each time a transaction is
completed using a specific tare ID, the selected weight value (gross or net weight) will be added to
the total and the corresponding counter will be incremented by one.
A tare memory can be recalled by picking from a list of all available records (accessed using the
Tare Table softkey). If the ID for the tare value is known it can be recalled directly by entering the ID
(note that ID entry is not case-sensitive) and pressing the Tare Table softkey. Unless the tare ID is
set as a number, an external keyboard is required to access a tare memory directly.
A printed report of the records in the Tare Table is also available. Additional details about the tare
table are explained in the IND780 Technical Manual Appendix C, Table and Log File Structure.
2.6.4.4.
Net Sign Correction
Net sign correction enables the terminal to be used for both shipping (inbound empty) and
receiving (inbound loaded) operations. Net sign correction can be either disabled or enabled on the
IND780. Refer to the IND780 Technical Manual, Chapter 3, Configuration, the Scale section, for
further information about disabling and enabling net sign correction.
If net sign correction is disabled in Setup, any stored weight value in the tare register is assumed to
be a tare regardless of the gross weight present on the scale at the time of the final transaction and
net values can be negative.
If net sign correction is enabled, the terminal will switch the gross weight and tare weight fields
when necessary, so that the larger weight is the gross weight, the smaller weight is the tare weight,
and the difference is always a positive net weight. Net sign correction affects the display, stored
data, weight recall, and printed data.
2-20
METTLER TOLEDO IND780 User's Guide
64057247 | 13 | 08/2014
Net sign correction will operate with pushbutton tare, preset tare, or tare memories. An example of

2.6.4.5.
Auto Tare
The IND780 can be configured so that tare is automatically taken (auto tare) after the weight on the
scale exceeds a programmed tare threshold weight. Auto tare can be configured in Setup as
enabled or disabled. When auto tare is enabled, the display changes to a zero net weight indication
after the weight exceeds the threshold value. The previous weight on the scale is stored in the Alibi
Table as the tare value. Auto tare operations involve:
• Tare Threshold Weight—When weight on the scale platform exceeds the tare threshold value,
and there is no motion, the terminal automatically tares.
• Reset Threshold Weight—The reset threshold weight must be less than the tare threshold
weight. When the weight on the scale platform falls below the reset threshold value, such as
when a load has been removed, the terminal automatically resets the auto tare trigger.
• Motion Check—A motion check is provided to control the re-arming of the auto tare function. If
disabled, the auto tare trigger will be reset as soon as the weight falls below the reset value. If
enabled, the weight must settle to no-motion below the reset threshold before the next auto tare
can be initiated.
Several conditions could inhibit the auto tare function:
• Motion—Auto tare cannot be taken when the scale is in motion. If motion is detected after the
weight on the scale exceeds a preset tare threshold weight, the IND780 will wait for a no-motion
condition. If a stable (no motion) weight condition occurs within three seconds, the auto tare
command is executed.
• Auto Tare Disabled—Auto tare can be configured in Setup as enabled or disabled.

Clearing Tare
Operating Instructions
Tare values can be cleared manually or automatically.
2.6.4.6.1.
Manual Clear
Manually clear tare values by pressing the CLEAR key
on the numeric keypad when the
IND780 is in the net mode and has completed the weighing operation. Motion on the scale will not
impact a manual clear.
If configured in Setup, pressing the ZERO scale function key
will first clear the tare before
issuing a zero command (refer to the IND780 Technical Manual, Chapter 3, Configuration, the
Scale section, Auto Clear).
2.6.4.6.2.
Auto Clear
The IND780 can be configured to automatically clear tare when the weight returns to a value below
a programmable threshold or by the print command. Once the tare is cleared, the display returns to
the gross weighing mode.
Auto clear is disabled or enabled in Setup. If auto clear is enabled, the following parameters as
configured in Setup affect the auto clear operation:
• Clear Threshold Weight—The clear threshold weight is the gross weight value below which the
IND780 will automatically clear a tare after settling to a value.
• Motion Check—A motion check is provided to control the automatic clearing of tare. If the
motion check is disabled, the tare value is cleared as soon as the weight drops below the
threshold weight (auto clear threshold), regardless of the motion status.
If Auto Clear and Motion Check are enabled in the Tare Auto Clear screen, once the Auto Clear
Threshold Weight value is passed and the then weight falls below the threshold (i.e. a load to be
weighed is placed on the scale and then removed), the IND780 will wait for a no-motion
condition then automatically clear the tare.
• Clear After Print—If enabled, tare is automatically cleared and the scale returned to the gross
mode after data has been transmitted by pressing the PRINT scale function key
or from a
remote source.
Refer to the IND780 Technical Manual, Chapter 3, Configuration, the Scale section, Auto Clear for
further information about configuring auto clear.
2.6.5.
Unit Switching
In order to support locations and applications that utilize multiple measurement units, the IND780
supports unit switching. The UNIT SWITCHING softkey
enables switching between primary units
(the main unit of measure) and alternate (primary or secondary) units. (For further information,
refer to the IND780 Technical Manual, Communication, Configuration, the Serial and PLC Interface
sections.)
When the UNIT SWITCHING softkey
is pressed, the display changes from the primary unit to the
secondary unit. The secondary unit may be a standard unit of measure or a custom unit. Custom
conversions support a division factor, a name and an increment size. An international standard unit
of measure should not be used as a conversion unit.
2-22
METTLER TOLEDO IND780 User's Guide
64057247 | 13 | 08/2014
When units are switched, the units value changes to the correspondingly selected units, and the
conversion of the display value occurs. The display division changes to an equivalent weight value
in the switched unit (for example, from 0.02 lb to 0.01 kg) and the decimal location switches to
accommodate the conversion.

IDNet Class II
Operating Instructions
If an IDNet scale base is set up as a Class II W&M approved scale with the appropriate capacity
and increment size, the IND780 will show a weight display with the last digit in a smaller size
(Figure 2-17).
Figure 2-17: Class II-Approved IDNet Base Weight Display
A demand print of weight data in this case will include parentheses around the last digit of each
weight field, to indicate the Class II approval condition.

2.767(8) kg
1.719(3) kg T
1.048(5) kg
Expand By 10
The EXPAND BY 10 softkey
is used to increase the selected weight display resolution by one
additional digit. For example, a weight display of 40.96 could increase by one additional digit to
display as 40.958. When the EXPAND BY TEN softkey
is pressed again, the display reverts
to the normal display of weight.
If programmed as approved with the metrology switch ON, the Expand By Ten mode is displayed
for five seconds then automatically returns to normal resolution. When the weight is expanded and
the terminal is programmed as approved printing is disabled.
If an IDNet scale base is set up as a Class II W&M approved scale via the IDNet Service Mode, the
EXPAND BY 10 mode is unavailable, and will not display when the softkey
is pressed.
2.6.8.
Print
The print function (demand print) can be initiated by pressing the PRINT function key
or by
automatic print. Demand printing of data may also be initiated as part of a particular sequence of
operation or special application software. A “Printing” message appears in the system line for 3
seconds when the terminal is carrying out a demand print command.

2.6.8.1.
Print Interlock
Print Interlock is designed to enforce a single print output per transaction. Print Interlock can be
disabled or enabled. If enabled, the print command is ignored until the measured gross weight
exceeds the print interlock threshold. After the first print command is executed, subsequent print
commands are ignored until the gross weight indication falls below the print interlock reset
threshold. If a print command is blocked by print Interlock, a synchronous “2nd Print Prohibited”
error is generated.
2.6.8.2.
Automatic Print
A demand print is automatically initiated when gross weight exceeds the minimum threshold and
there is no motion on the scale. After initiation, gross weight must return below the reset threshold
before a subsequent automatic print can occur.
If Automatic Print is enabled, it can be triggered and reset by weight exceeding thresholds, or by
weight deviation from a previously stable reading.
2.6.8.3.
Repeat Print
The Repeat Print softkey
permits the output of the most recent transaction, or of a Custom
Print from an application, to be printed again with a DUPLICATE header or footer to distinguish it
from the original print.
Output templates can be flagged with a DUPLICATE header or footer to indicate that the data in the
output template was generated as a repeat of a previous print transaction.
In firmware versions 6.5xx and above, the last printed data used for the Repeat Print function is not
retained during a power loss so the Repeat Print function will not be available after power is cycled
until after a print is generated.
2.6.9.
MinWeigh
Certain industries such as pharmaceuticals and food require a guarantee that the weighing
equipment selected for a particular measurement is adequate for the task. One way to ensure that
appropriate weighing equipment is selected is by creation and use of a minimum weighment value
(MinWeigh), below which a particular piece of weighing equipment cannot be used.
When the MinWeigh function is enabled, the MINWEIGH softkey
allows modification of the
MinWeigh value without entering Setup. If security has been enabled, a valid user must log in
before a change can be made.
The IND780 compares the current net weight with the programmed MinWeigh value. If the net
weight is greater than or equal to MinWeigh, all equipment functions behave normally. If the
absolute value of the net weight is less than MinWeigh, the weight display includes an icon ( ) to
the left of the weight, and the weight display appears in red. If the user attempts to record the weight
while in this condition, the printout includes an asterisk (∗).
For specific step-by-step instructions on how to setup MinWeigh, see the Scale | MinWeigh section
of Chapter 3, Configuration, in the IND780 Technical Manual.

2.6.11.
Target Comparison
Target comparison is used to compare either the gross or net weight on the scale to a
predetermined target value. This feature can be useful in both automatic and manual processes. As
an example, an automatic filling system using target comparison could provide a Start signal to the
IND780 and the IND780 could control the feeder system to fill a container to a desired target.
An example of a manual process could be a checkweighing station where an operator is checking
net weight of packages. The IND780 can use its target comparison feature to provide a graphical
Over - OK - Under indication to help the operator determine if the weight of each package is
acceptable or not compared to an ideal weight.
Target (setpoint) comparison is most often used in two types of applications:
• Material transfer applications—Requires that a control device deactivate when a target value is
achieved
• Over/Under applications—Classify a load placed on the scale platform as above or below the
target value or within the target tolerance range
The IND780 target comparison rate (for analog load cell scales) is 50 comparisons per second.
The comparison rate for high precision IDNet bases depends on the module in the base.

2.6.11.1.
Material Transfer Applications
If the target comparison of the IND780 will be used to control the flow of material, the application
can be classified as a Material Transfer application. These types of applications are usually
automated but can also be manual. A single or two-speed feeding system is used to either add
weight to or remove weight from the scale. The terminal monitors the change in weight and
compares it to a previously entered target and other control parameters.
Table 2-5 defines some terms used in Material Transfer applications.
Table 2-5: Terms used in Material Transfer applications

Explanation
Abort
After a target comparison process has been paused, it can be totally stopped by
pressing the Abort softkey
under the Target Control softkey
or by triggering a
Target Pause discrete input. If abort is selected, the target comparison process is
aborted.
Coincidence
Outputs
A coincidence output is always active and does not require a start or stop signal. If the
weight on the scale is below the target minus the spill value, the outputs are “on”. If
the weight is above the target minus the spill value, the outputs are “off”. This type of
output typically requires external logic to provide the required control for feeding
systems.
Concurrent
Outputs
This describes the operation of the feed output in a 2-speed feeding system. If the
feeder type is programmed as concurrent, both the fast feed and feed outputs are
active at the beginning of a target comparison. When the weight reaches the point at
which a slower feed is to occur, the fast feed output is turned off.
Fast Feed
Output
This refers to the physical output connection that is used for the faster feed in a 2speed feeding system. This output is not used in a single speed feeding system.
Feed Output
This refers to the physical output connection that is used for the slower feed in a 2speed feeding system or the only feed output in a single speed feeding system.
Fine Feed
The value entered for the amount of material that will be fed in the slower rate of feed
in a 2-speed feeding system. This value and the spill value are subtracted from the
target to determine the point that the fast feed output turns off.
Independent
Outputs
This describes the operation of the feed output in a 2-speed feeding system. If the
feeder type is programmed as independent, the feed output does not turn on until the
fast feed output turns off. Only one feeder output is active at a time. It is the opposite of
concurrent outputs.
Latched
Outputs
Latched outputs turn off at the target weight minus the spill value and remain off
(regardless of additional plus or minus weight changes) until a “start” signal is
received. These types of outputs do not usually require external logic to perform
standard weigh-in or weigh-out sequences.

Explanation
Material
Transfer
Mode
The target comparison mode that provides control for delivering a measured amount of
material from one container or vessel to another. The transfer can apply to material
entering or leaving a container or vessel. It covers applications traditionally using
terms such as weigh-in, weigh-out, filling, and dosing.
Pause
A pause function is provided in target comparison control in case a target comparison
must be temporarily paused. This can be done by pressing the Pause softkey
under the Target Control softkey
or by triggering a discrete input programmed as
Target Pause. When paused, power is removed from the Feed and Fast Feed (if used)
discrete outputs. After a target comparison has been paused, the process can either be
resumed or aborted.
Resume
After a target comparison process has been paused, it may be resumed by pressing
the Resume softkey
or by triggering a discrete input programmed as Target
Resume. When a target comparison is resumed, it continues to use the original target
values.
Spill
The amount of material that will be added (on a weigh-in) or removed (on a weighout) from the scale after the final feed is turned off. In a weigh-in process, this is the
material in suspension that will still fall onto the scale when the feed is turned off. This
value is subtracted from the target value to determine when the feed output turns off.
Start
When using latched targets, the default condition is with the latch set or in the “off”
condition. To turn any outputs “on”, a start signal is required. This could be the Start
softkey
softkey
2.6.11.1.1.
, a discrete input programmed as Target Start, or via the Target Control
.
Target
The target is the weight value that is the end goal of the material transfer process. If a
container should be filled with 10 kg of material, the target value is 10 kg.
Tolerance
The weight range above and below the target value that will be acceptable as an “in
tolerance” target comparison. The tolerance can either be entered as a weight
deviation from the target or a percentage deviation from the target, depending upon
setup.
Target Control
Two different levels of target control are provided by the terminal for the Material Transfer mode.
Latching outputs must be enabled to utilize either type of automated control. For simple
applications, no control is provided. The comparison runs at all times. Whenever the scale weight
is less than the target value, the output is True/enabled.
For those applications where latching outputs are used or more control is needed for an occasional
pause or to abort a comparison process, the TARGET CONTROL softkey
is used. Pressing the
TARGET CONTROL softkey provides a dedicated display for the target comparison with the
comparison status and appropriate softkeys shown. Possible status modes are “Ready”, “Running”
or “Paused”. The appropriate control softkeys include START
, PAUSE
, and STOP
. Target
control functionality does not work when coincidence targets are configured.
When the weight data is invalid (e.g. under zero, over capacity), the Target Control screen will
show a status with dashes (- - - - -) and only the BACK softkey
will be available.

Over/Under Applications
Operating Instructions
If the target comparison of the IND780 will be used to checkweigh the weight of a product, the
application can be classified as an Over/Under application. These types of applications are usually
manual processes but can also be automated. The SmartTrac display indicates the classification of
the weight placed on the scale and discrete I/O can be used to trigger external lights or other
controls. The terminal compares the current weight to a previously entered target with tolerance
values, or to zone limits; it then indicates the results. In Table 2-6 definitions will explain some
terms used in Over/Under applications, and are specific to those applications:
Table 2-6: Over/Under Applications Terms
Term
2.6.11.3.
Explanation
Over Limit
If a tolerance mode of “Weight value” is selected in Setup, the IND780 does not require
the entry of a target value. In this mode, only the upper and lower limits for the OK
zone are entered. When programmed for this mode, the over limit value is the
maximum weight that will be classified as OK. Any weight above this value will be
classified as Over.
Over/Under
Mode
This target comparison mode provides three zone classifications for weight placed on
the scale. The classification can be Under if the weight is below the target minus the tolerance, OK if within the tolerance range or Over if the weight is above the target plus
the +tolerance.
Target
The target is the ideal weight value for the product being tested. If a container should
weigh exactly 10 kg, the target value is 10 kg.
Tolerance
The weight range above and below the target value that will be accepted as “OK” in the
target comparison. The tolerance can either be entered as a weight deviation from the
target, a percentage deviation from the target or as absolute weight (zone edges)
depending upon setup.
Under Limit
If a tolerance mode of “Weight value” is selected in Setup, the IND780 does not require
the entry of a target value. In this mode, only the upper and lower limits for the OK
zone are entered. When programmed for this mode, the under limit value is the
minimum weight that will be classified as OK. Any weight below than this value will be
classified as Under.
Zones
The IND780 provides 3 different classifications or “zones” in the Over/Under mode. The
zones are Under, OK and Over.

Comparators
Comparators are simple targets, twenty of which can be configured in setup. They are controlled
either by coincidence or by comparison with a target or range. The source for comparison can be
the Gross Weight, Displayed Weight, Rate or assigned by a custom TaskExpert application. When
assigned to the home screen, the Comparator softkey
permits direct access to the Comparators
for the current selected scale. As seen in Figure 2-22, this screen displays each Comparator’s ID,
Description, Limit, Units, High Limit (if applicable) and Active operator, provided that they have
been configured in setup.
To make changes to a Comparator directly from the home screen, if the Comparator ID is known,
press the ID number and then the Comparator softkey
. If the ID is not known, press the
Comparator softkey
, use the UP/DOWN keys to select the desired Comparator from the list, and
press the Edit softkey
. Only the limit value/s can be edited. To edit parameters other than limits,
the Comparator configuration screen must be accessed in setup.
Figure 2-22: Comparators List for Scale 2
When the Active operator value is <, <=, =, < >, >= or >, the selected source is compared to a
target weight. When the Active value is within (>_ _<) or outside (_< >_) a range, the selected
source is compared to a range defined by the Limit and High Limit values.

2.6.12.1.
Using Comparators
To use a Comparator, it must be assigned to a discrete output. Comparators are not associated
with SmartTrac.
2.6.12.1.1.
Target Value Comparators
In this case, the output will be triggered depending on the Active setting. For example, if the Active
operator is < (less than) and the Limit is 1000 kg, the output will turn OFF when the measured
value reaches 1000 kg.
2.6.12.1.2.
Range Comparators
In the case of a Range mode Comparator, the Limit value sets the lower of the two limits that define
the range, within or outside (depending on the operator) which the output is active. For example, if
the Active operator is Within (>_ _<), the Limit is 3.0 kg/sec and the High Limit is 8 kg/sec, the
output will be active provided the rate remains between 3 and 8 kg/sec. If the rate falls below 3 or
exceeds 8 kg/sec, the output will turn OFF.
Note that comparisons using a Rate source require the rate calculation to be enabled and the
Rate display to be turned on. The Rate value configured in setup at Scale > Rate permits weight
and time units to be defined, together with the period between individual measurements and the
period over which the measurements are averaged to generate the output value.
A Range Comparator can also use Displayed or Gross weight as its source. For example, if
displayed weight (possibly a net value, allowing for the weight of a hopper) is the source, the
Active operator is Outside, and the Limit and High Limit are 1000 kg and 1500 kg respectively, the
output will remain active as long as the source value is below 1000 kg or above 1500 kg. In this
case a large enough value for the High Limit should be set to ensure that, once the Limit is reached
and the output turned off, there is not sufficient spill to reach the High Limit and reactivate the
output.
2.6.13.
ID Mode
The ID function provides a convenient and simple way to ensure that a specific sequence of
operation is carried out the same way each time. Each step can include an on-screen message that
instructs the operator to perform an action, or a prompt asking the operator to enter some
information for a transaction printout. These steps may include data entry (using the numeric
keypad, alphanumeric keys, or some other input such as a barcode scanner) and actions (such as
placing a package on the scale, taking a tare, or printing a ticket for the transaction). When a step
is completed, depending on the type of step it will either automatically advance or pressing the
ENTER key moves it to the next step.
The following list shows the types of steps that are programmable in a sequence.

The IND780 supports two separate ID sequences, ID1 and ID2. As many as 20 steps may be
programmed in each sequence, and the sequence can be triggered in one of two ways:
•
Manually, using the ID softkeys
or
, application keys A1-A4, discrete input or
shared data triggers xc0149 (ID1) and xc0150 (ID2).
•
Automatically, by threshold and reset weight readings from the pre-defined scale.
If the sequence is triggered manually, it may be programmed to continuously loop using the Start
is pressed or an ESC softkey
Sequence step, repeating all steps until either the EXIT softkey
is pressed while an alphanumeric entry field is selected.
When ID mode is set to function automatically, placing on the pre-defined scale a weight that
exceeds a pre-configured threshold value initiates the respective sequence. When all the steps have
been performed or the sequence is exited and the weight is removed, the reading from the scale
falls below a user-defined reset value. At this point the terminal is ready to begin the next ID
sequence.
Only one ID sequence can be triggered to run at a time. Starting an ID sequence while one is
currently running will generate a system line message indicating that the ID sequence is busy. If a
step fails to execute due to an invalid operation (eg. print connection not found, or tare too small),
the ID sequence will be exited automatically and will need to be restarted.
Typically the step’s number, prompt and operator data entry box (if applicable) appear together for
each step in the Message Area below the weight and SmartTrac display (if enabled). Considering
space restrictions, the terminal will attempt to resize resize its on-screen objects to fit the prompts
and data entry box, as shown in Figure 2-23 below. If an automatic resize is not possible, the

SmartTrac™
SmartTrac is a graphical display visualization of either the displayed weight or gross weight as
selected in Setup. The visualization may be a bar graph, cross hairs, or an over/under display. The
following conditions allow SmartTrac to display:
• A Target must be defined and selected.
• A SmartTrac size other than none must be selected at Setup > Terminal > Display.
• A SmartTrac graphic display type must be selected for the scale at Setup > Application >
Operation > Target > Scale #.
Refer to the IND780 Technical Manual, Chapter 3, Configuration, for details about these settings.
2.6.14.1.
Display Sizes
Figure 2-25 shows a small size SmartTrac bar graph. Figure 2-26 shows an over/under display in
medium size and Figure 2-27 a cross hairs display in large size. Note the effect on the main weight
display area. In each of these examples, the display shows the weight on target. The small bar
graph does not include target weight, description and tolerance information; with a medium or large

Display Colors
• Red—Over tolerance
• Green—Within tolerance
• Blue—Under tolerance
In cross hairs mode, the colors listed above are used as background fill. In this case, the cross
hairs appear in white when within tolerance (see Figure 2-27), and yellow when over or under
tolerance.
2.6.14.3.
Bar Graph Mode
The operator adds material until the measured value is within an acceptable tolerance limit.
Normally an operator will add material quickly when the container is not nearly full and more
slowly as the target value approaches. Figure 2-28 shows a SmartTrac bar graph with a displayed
value below the lower tolerance limit.
Figure 2-28: Bar Graph, Large SmartTrac Display
While the display appears to be one continuous bar graph, it can actually be broken into four
separate sections or ranges. Depending upon the target and tolerance values used, there could be
one, two, or three speeds at which these graphical sections are filled in. Figure 2-29 illustrates the
ranges, and includes the numerical display of the target and tolerance values. Note the white
triangle, indicating that in this case the measured weight is precisely on target.

2.6.14.3.1.
Under Tolerance
The Under Tolerance range is labeled “A” in Figure 2-29, and represents the amount of material
between 10% of the target value and the target minus the negative tolerance value. The bar graph
begins to populate the “A” range when more than 10% of the target has been added. Until the 10%
point is reached, no fill is shown.
2.6.14.3.2.
Acceptable Tolerance Under Target
Region B in Figure 2-29 represents the zone of acceptable tolerance below the target value.
2.6.14.3.3.
On Target
When the measured value exactly equals the target value, an unfilled triangle indication displays,
as shown in Figure 2-29.

Acceptable Tolerance Over Target
Region C in Figure 2-29 represents the zone of acceptable tolerance above the target value.
2.6.14.3.5.
Over Tolerance
Region D in Figure 2-29 represents the zone of unacceptable tolerance above the target value. In
Region D, the fill rate reverts to the same rate as used in Region A. If the measured value is large
enough that the number of dot columns required for display exceeds the number available, the
display saturates. Further increases in the measured value do not affect the graphical display.
2.6.14.4.
Over/Under Mode
The Over/Under SmartTrac visualization may be displayed in medium or large sizes. If the Target
Table’s Tolerance Type is Target Deviation or % of Target, the target value and the amount of
deviation from it are shown, together with a graphic indicating the direction of deviation (Figure
2-31 and Figure 2-32). If the Target Table’s Tolerance Type is Weight Value, only the graphic
display appears indicating whether the current value is above, within or below the acceptable range
(Figure 2-34). In either case, a black oblong indicates that the current weight is within the
acceptable range.

address and a terminal number. Within a cluster, terminals can share Shared Data, operator
consoles, printers, and PLC interfaces. The IND780 also extends its clustering services to host PCs
or file servers on an Ethernet LAN for data exchange.
An IND780 terminal can operate as a remote operator console to any clustered IND780. A
dedicated SELECT TERMINAL softkey
, assigned to the home screen, can be pressed to open a
list of names of clustered terminals. Once a terminal is selected, pressing OK
allows the local
terminal to access the display, keypad and setup configuration of the remote terminal. The local
terminal’s display is replaced with that of the selected remote terminal. All front panel keys now
function as if they belonged to the remote terminal, and softkeys assigned on the remote terminal
appear on the home screen. The local terminal will not lock out the controls for the remote terminal
during this remote connection.

Firmware Upgrade Procedure
There are two ways to install an upgraded version of the IND780’s firmware. The preferred method
uses the PC-based InSite™ software tool, but it is also possible to do so without a computer, using
a USB flash memory drive (thumb drive) connected to the IND780’s USB port.
3.4.1.
Upgrade Using InSite™
To upgrade existing installed field units, two upgrade files (Upgrade.L78 and Upgrade.Z78) are
required. These files and the method described below can only be used if you are upgrading from
IND780 revision 3.xx or higher and the terminal has at least 256MB of CF card memory.
If the terminal has a 2.xx or lower revision firmware or a smaller CF card memory, the upgrade
operation requires a re-format of the CF memory card and a complete flash of the new firmware files
and folders structure. For this condition, contact a local METTLER TOLEDO representative for
assistance in upgrading your terminal.
With the IND780 connected to a network:
1. Run the InSite Configuration Tool (only version 5 or higher).
2. In InSite, access Home | Connection I Settings, or click the Settings icon
address the terminal.

Power Up and Screen Saver Graphics
The graphic used by the IND780 as a splash screen during start up and the image used as a
screen saver (which displays when the Screen Saver setting at Terminal > Display has a value
other than zero) can both be changed by downloading replacement files to the terminal’s UPGRADE
folder.
3.4.3.1.
Power Up Graphic
The graphic used at power up must be a bitmap file measuring no more than 320 pixels wide and
140 pixels high. It must be named pwrup.bmp.
3.4.3.2.
Screen Saver Graphic
The screen saver graphic is also a bitmap file, which may be in 256 color format. The image
should measure no more than 320 pixels wide and 200 pixels high, and must be named
saver.bmp.
3.4.3.3.
Installing New Graphics
Either or both of the power up and screen saver graphics can be installed on the IND780 by
making an ftp connection to the terminal via EtherNet, logging on as an administrator (with write
privileges), and copying the file/s to the UPGRADE folder. When the terminal is restarted, the files
are automatically moved to their correct location, where they replace the existing images.
3.5.
System Backup and Restore Procedures
The configuration of an IND780 may be exported (backed up) to and restored from, USB memory.
Files can be restored to the original terminal or copied to another IND780, which acquires a
configuration identical to that of the original. This permits the restoration of setup should a main
PCB require replacement, for example, and allows the creation of functionally identical terminals.
Once the backup dataset is copied to a USB drive, it can be saved to a PC. However, for
restoration to an IND780 the file must always reside in the directory indicated below.
3.5.1.
Backup
When the IND780 is backed up, the dataset includes all log files in .csv format. These can be
viewed or printed from a PC.
To back up files from an IND780:
1. Connect a USB (flash) memory device to the IND780’s USB port, either directly or via a USB
extension cord.

2. Access Setup > Maintenance > Run > Backup to USB. The screen shown in Figure 3-6 will
appear.
Figure 3-6: Backup to USB
3. By default, the Dataset Name is BK1; press ENTER to select the field and enter another name, if
required.
4. Press the START softkey
. The IND780 will check for the presence of a valid USB memory
device. On finding one, it checks for available space. If a device is not found, or a device is
present that has insufficient space for the operation, a prompt (“USB Memory Error”) informs
the operator and the backup does not proceed. If space is available, the IND780 creates a
folder titled Mettler Toledo/Backup/IND780/ <dataset name > (where “dataset name” is the
name entered in step 3), then begins the transfer of data. An on-screen message (“Working”)
indicates that the procedure is in progress.
5. Once the terminal indicates that the backup is complete, the USB device can be unplugged and
the EXIT softkey
pressed to return to the menu tree.
3.5.2.
Restore
System Restore cannot be performed if the terminal is locked.
An Administrator level login must be in effect to carry out this procedure.
A system restore operation does not copy log files from the dataset, and the terminal’s existing log
files are not over-written on restore.
To restore files to an IND780:
1. Connect a USB (flash) memory device to the IND780’s USB port, either directly or via a USB
extension cord.

3. Press ENTER to select the Dataset Name field, then use the alphanumeric keys or an external
keyboard to enter the name of the dataset to be uploaded to the terminal.
4. If scale calibration parameters are to be included in the restore procedure, select Enabled in the
Restore Scale Calibration box.
5. Press the START softkey
to initiate the transfer of files. The IND780 will check for the
presence of a valid USB memory device and for the existence, in a folder named /Mettler
Toledo/Backup/IND780/<dataset name>, of the file named in step 3. It then begins the transfer,
with an on-screen message (“Working”) showing that the procedure is in progress. If a USB
device is not found, or the named dataset is not present in the correct folder, a message
(“Could not find Dataset Name, please re-enter.”) appears.
6. Once the terminal indicates that the transfer is complete, the USB device can be unplugged and
the EXIT softkey
pressed to return to the menu tree.
7. It may be necessary to restart the terminal in order to complete the restore operation.
3.6.
Service
Only qualified personnel should perform installation, programming, and service. Please contact a
local METTLER TOLEDO representative for assistance.
In general, once the IND780 is installed, programmed, and calibrated for a given application, only
routine calibration service is required.

RS-232 Serial Output Voltage Test
If the send and receive functions of the serial (COM) ports test fail, use the following procedure to
determine whether the RS-232 serial port is operational:
1. Disconnect AC power from both the IND780 terminal and the printer.
2. Disconnect the serial cable from the COM port on the IND780 main PCB.
3. Set the voltmeter to read 20 VDC.
4. Connect the red lead to the transmit terminal of the COM port and connect the black lead to the
ground terminal of the COM port.
3-16
METTLER TOLEDO IND780 User's Guide
64057247 | 13 | 08/2014
5. Apply power to the IND780. The meter should read as follows:
•
Demand mode—The meter should read a stable value (without fluctuation) between −5
and +15 VDC.
•
Continuous mode—The meter should fluctuate continuously within the range −10 to +10
VDC. The actual values and degree of fluctuation observed will depend on the type and
sensitivity of meter used. The constant fluctuation on the meter display indicates that the
scale/indicator is transmitting information.
To test Demand baud rates, press the PRINT key
. The display should fluctuate as for
continuous mode for the duration of the transmission, then become stable again. This fluctuation
indicates the terminal has transmitted data.
When measuring the higher baud rates in the Demand mode, the meter display will fluctuate for
a shorter period of time.

Calibration Values
Displays the current calibration values for each scale. If these values are recorded after a scale
calibration, and the scale channel PCB is replaced in the future, the calibration values can be
manually entered here to “transfer” the previous calibration to the new scale channel PCB. This is
not available with IDNet bases.

Shift Values
Used for POWERCELL and PDX scales only. The following screen shows values used to adjust gain
for each load cell in a multiple load cell system. The values compensate for difference in response
between cells. The load cell numbers represent the node cell addresses. Where more than 12 load
cells are present this screen displays a scroll box to reveal further rows.
The diagnostic purpose of the Load Cell Output and Shift Values screens is to permit a technician to
confirm valid calibration values were obtained when the calibration routine (Setup > Scale > Scale
n > Calibration) was carried out.

is being diagnosed has a known address, select that address from the Load Cell Address selection
box. If the cell address is unknown, then select Connected Cell. If the cell is faulty or it has an
invalid address, the terminal will fail to communicate with the cell. If the cell responds correctly, the
node address and the cell counts will be displayed on the screen (Figure 3-24).

Statistics
Displays statistical information for each scale such as the total number of weighments, the number
of scale overloads, the peak weight weighed on the scale, the total number of zero commands, and
failed zero commands (Figure 3-25). These are very helpful when diagnosing scale problems.
These statistics accumulate for each scale, and are saved until a master reset is performed. It is not
considered likely that a master reset will be a frequent occurrence, so these statistics are effectively
permanent.
Statistics cannot be deleted without losing all other setup values.

the corresponding temperature value.
Figure 3-32: Scale Load Cell Temperature Screen
The PDX cells rely on their temperature sensors to compensate for temperature variations and
continuously provide accurate weight measurements. To ensure that the sensors are operating
correctly, it is important to compare the temperature readings between the load cells. Readings
should be reasonably close between the cells if there are no obvious differences in external
influences (e.g. sunshade, heating pipes).

Scale Load Cell Supply Voltage
From the MT Service View screen, choose Scale in the Device selection box and Supply Voltage in
the View selection box. Select the PDX scale channel to view and press the VIEW softkey
to
display the Scale Load Cell Supply Voltage screen. This screen provides a view of the input supply
voltage readings measured in every PDX cell for the selected scale. For each cell node address, the
corresponding supply voltage value is shown in volts. Measurements are automatically updated
hourly, and after power-up.
Figure 3-33: Scale Load Cell Supply Voltage Screen
The nominal supply voltage is based on whether the IND780 uses its internal 12 VDC or the
external 24 VDC supply to power the cells. It is normal to have the voltage readings from one
cell to another drop in value. This is the result of the additional power consumption attributed to
each cell on the network and the voltage dissipation along the length of cabling. The expected
load cell supply voltage ranges are:
• At 12 VDC: 12.5 – 7.9 VDC
• At 24 VDC: 24.5 – 15 VDC
Most importantly the supply voltage measured at any cell must not be below 7.8 VDC for the PDX
cell to operate reliably. Wiring shorts or an overloaded supply will cause these readings to be out of
range. A system that has supply voltages that deteriorate over time may also indicate a potential
problem.

softkey
to proceed to display the Scale Load Cell COM Voltage screen. This operation will take
several minutes as each load cell is required to interrupt its communication lines temporarily in
order to take CAN voltage measurements.
This screen provides a view of the CAN-High and CAN-Low signal voltages measured in every PDX
cell when they are placed into the Dominant and Recessive communication mode. For each cell
node address, the corresponding CAN signal voltage values are shown in volts. Measurements are
static and are only updated each time this screen is viewed.

Watchdog Monitoring
The main hardware microprocessor of the IND780 has a built-in hardware watchdog timer that is
used to constantly monitor the performance of the measurement channels, weight display,
peripheral communications and the discrete I/O functions. If any one of these functions fails to
respond to the watchdog within a fixed time interval, the watchdog timer will timeout and the entire
terminal will automatically reboot within 40 seconds. Given the seriousness of the system failure, if
feasible the terminal will record the watchdog update failure event in the error log. Watchdog
monitoring allows the terminal to detect certain system failures and to automatically recover from
them.
3.7.11.
Master Reset
A hardware master reset switch is provided, that sets all IND780 terminal settings to the factory
default settings (see Appendix B, Default Settings). This includes scale setup and calibration
information, log files (except for the error log) and counters. The master reset typically is performed
under these circumstances:
• When a hardware configuration change is made, such as adding a new scale or Discrete I/O
board to the terminal.
• When a software configuration problem arises that cannot be resolved without starting from the
factory default settings.
• When security is enabled to protect setup, and the password is lost.
• After a firmware upgrade is performed.
• After a hardware key is installed or removed.
Two types of master reset are possible, depending on the position of switch S2 (shown in its
OFF position in Figure 3-50): A full reset including metrologically significant scale configuration
data, and a reset that preserves scale data.
